This is no use to you at all, but thank you for:

* Reminding me that Ruby doesn't need parenthesise; I like the  
'assert_euqal's without them a lot.
* Showing me that 'assert_equal' (and the others, I'm sure) will  
accept a third descriptive argument - I didn't know that, and I can  
see it's useful!

I've just started trying to use TDD, and so far I am very impressed.  
What I like about it is how much it makes me think about what I'm  
doing, rather than how I'm going to do it. I can see that it is a  
discipline that is going to need a lot of practice though; it's  
already given me benefits, but I do find it hard at the moment.

Interestingly, there are a few things I've been trying to build  
without TDD for a while. I've sat down and tried to do them with TDD,  
and it has been very helpful, in that I've got no where :) Basically,  
I've realised that I don't _really_ know what I'm trying to do; and I  
need to know that before I can work out how to do it.

I think I also need to learn to be a bit less strict, and just get on  
with it. Write a test for something that seems about right, and be  
prepared to chuck it all out if I find I'm barking up the wrong tree,  
or I've not quite got the right slant on what I'm trying to do.

Cheers,
